Introduction
This portfolio is a compilation of the skills I have developed in VIS 2128 - Spatial Analysis at Harvard’s Graduate School of Design for my Master in Urban Planning Program. This series of maps includes the following skills, and was developed directly in RStudio:
- Displaying multiple vector layers on the same map
- Calculating and displaying relationships among point and polygon layers based on distance
- Aggregating point data to a layer of polygons
- Calculating and displaying accessibility, based on travel time
- Converting between raster layers and vector layers
- Displaying raster data on a map
- Georeferencing a raster image
- Displaying data on an interactive map
Georeferencing
These are 2 maps created via georeferencing in QGIS. Map 1 displays the FEMA flood zones for Miami Dade County overlaid on a georeferenced map from the Harvard Maps Archive. Map 2 is a georeferenced historic map of Cambridge, MA from 1894, overlaid with a current zoning map of Cambridge. The map demonstrates the following skills:
- Georeferencing a raster image
